2 WHAT IS IRIDIUM FLOW CONTROL? Iridium is a platform for configurable flow control. Its modular design allows for a single device to adapt to a variety of flow conditions and applications C1 Configuration Though the Iridium is modular and can be built in many configurations, there are several common setups offered as factory configurations. This brochure discusses the C1 Configuration for Liquids, which features a PTFE microturbine flow sensing module (A601) and a PTFE proportional diaphragm flow control module (B601). This configuration can be set up to control liquid flow ranges as low as 7-50 ml/minute and as high as L/minute. Other configurations can be custom built as desired. How Does a Flow Controller Function? Flow controllers use an integrated flow rate sensor and control valve to regulate flow rate regardless of inlet pressure fluctuations. A flow control setpoint is provided a) by a user via the touchscreen, or b) remotely via an electronic signal. The controller then adjusts the integrated valve as needed to maintain the desired flow rate.

3 Multiple I/O Options USB and RS485 interfaces are standard. Analog (ma or VDC) and relay outputs available as options. Liquid Flow Ranges Flow ranges as low as 7-50 ml/minute and as high as L/minute are available. PTFE Flow Path Wetted materials of only PTFE, sapphire and Viton (Kalrez optional) ensure compatibility. INTEGRATED TOUCHSCREEN PELTON MICROTURBINE FAST CONTROL LOGIC EXPANSION SLOTS Using the integrated 3.2 color touchscreen, users can display flow rate, totalized flow, alarm states, and more. Most configuration settings can be modified via the screen, including engineering units, set points, and calibration curves. Settings may be accessed by USB if the touchscreen is not accessible. For repeatable liquid flow measurement, the A601 flow module uses a miniature PTFE microturbine wheel suspended on a sapphire shaft. An infrared beam detects the rotation speed. The zero-friction design provides fast response and no particle generation. By utilizing advanced microprocessors and specially designed software, the Iridium flow controller is able to react to both small and large changes in supply pressure or setpoint and adjust the flow rate almost instantly. Smart logic minimizes overshoots and erratic valve actions. As part of its modular construction, the Iridium platform has two open slots for expansion cards. Features include analog I/O, wireless communication, error outputs, and can also be customized as needed. Two cards can be used simultaneously. Just like the flow modules, expansion cards can be installed by the user. Sample Applications On-demand chemical dilution and blending Sample flow rate regulation Consumable usage monitoring and regulation

4 MODULAR FIELD-SERVICEABLE If you need to swap a module or change a fitting type, the change can be made in the field with no need to return to the factory. VARIOUS CONFIGURATIONS Because changes can be made so easily, users can use one Iridium for multiple ranges and configurations. CHANGING MODULES Step 1: Remove Case Step 2: Remove Main Electronics Step 3: Remove Module(s) Step 4: Install & Reassemble The two halves of the case can be separated by removing only six bolts and two lock rings. The case will then slide off. For easier access to the modules, the display and main electronics can be removed with three bolts. Unplug cables as needed. The module track is held together using two special bolts. Once those are removed, each fluid module is free to slide out. The new modules can easily be installed by sliding on the track. The previous steps are then reversed to reassemble. AVAILABLE OPTIONS AND UPGRADES ANALOG I/O MODULE: Enables the Iridium to receive and transmit analog signals such as 4-20 ma, 0-20 ma, 0-10 VDC, etc. All signals are fully isolated. ALARM OUTPUT MODULE: Enables the alarms that are built-in to the Iridium to be transmitted externally via relay contacts. WATER PROOF MODULE: Provides splash protection (up to IP65) for the Iridium by encapsulating all electrical connections.

5 FLEXIBLE GRAPHICAL INTERFACE Through the integrated 3.2 touchscreen, the user can program setpoints, display current status, and adjust configuration while the unit continues to control flow rate and provide output. Where required, the touchscreen can become a digital keypad for simple numeric value entry. SOFTWARE UPDATE The Iridium platform can easily be upgraded through downloadable firmware updates via the standard USB interface. In addition, the factory can provide customized software packages with unique configurations to match specific applications or process conditions. I/O OPTIONS RS485 serial interface and Universal Serial Bus (USB) interfaces are standard. The Iridium also has two internal expandable card slots. A popular option is the Analog I/O module, which provides isolated ma or VDC I/O for setpoint (input) and current flow rate (output) communication. MODULAR DESIGN FLOW RANGES FITTING CHOICES The Iridium platform supports field-replacement of internal modules as needed, allowing the users to swap flow ranges, valve types, I/O modules, and more as application conditions change. These swaps take only minutes and provide virtually limitless configurations. With the Iridium C1 configuration, flow ranges for liquids are available as low as 7-50 ml/minute all the way up to L/minute. Most ranges feature a 1:10 turndown (or better) and repeatable, accurate control can be expected across the entire specified range. The modular design of the Iridium also allows for inlet and outlet fitting sizes and types to be changed as needed. FNPT, compression, flare, and other fitting types are available in sizes as small as 1/8 or as large as 1/2. Metric sizes may also be available upon request. KALREZ SEAL KIT: Replace the standard Viton seals with Kalrez for enhanced chemical compatibility. TILT STAND: Bracket that supports the Iridium on an angle for easier use of the display in a laboratory environment. INTEGRATED MODEL: Contact factory for details on the Iridium Industrial, which separates the display from the fluid components.
